Compressed, but their extreme edges above and beneatl), occa- 
®‘oned by the upper and lower part of the fish being slightly flat- 
^®ned, and appearing somewhat truncated. Tliis character, ob- 
®®tvable in Cepola Taenia, is equally obvious in rubescens, and may 
^ at once perceived when the dorsal and anal fins are expanded. 
Th 
^ commencement even of the carinations along the upper part 
*^g>ns before the dorsal fin, taking their rise from the back of the 
^®^d in an oblique course, gradually approximating towards the 
ray of the dorsal fin, and thence continuing pretty near the 
of that fin at each side throughout the whole length of 
fish. The carinations beneath are likewise contiguous, and 
close to the base of the anal fin on each side. — The la'st dif- 
ference alluded to, consists in the number of the teeth ; those in Ce- 
P°la rubescens constituting only a single series in each jaw, while 
Cepola I'asnia the lower jaw has a double series. We cannot 
®urcly admit this as an absolute distinction, when it is remembered, 
the number of teeth increases in many fishes as they advance 
iti age; and that the lower jaw of our C. rubescens presents a 
broader space than the upper ; it is possible the latter may have more 
one row of teeth when full grown, and that our fish has not 
yet attained to perfect maturity.

Every circumstance considered, it will be allowed that neither of 
*^^6 above characters are sufficient to authorise us in forming two spe- 
of C.Tamia and C.rubescens ; the characters proposed accord with 
^eth. 'WTe are still, inclined to allow that the difference between 
colour of the two fishes is very remarkable ; and that, hould 
delineation of Cepola Taenia given by Bloch be correct in all 
*^®®pects, we ought not too hastily decide on their being of the
